This invention relates to a calculating machine in which a transmission device is arranged between at least one of the totalizers on a carriage and a storage device. The storage-device.

comprises a rotary member supporting storage gears and arranged transversely with respect to the axes oi the numeral wheels in the totalizer and to the axes of the storage gears.

Machines of this type are known as, for instance, from the patent to Pott No. 2,173,635 but, as designed heretofore, they have the drawback that the values in the storage device cannot be inspected, since it is difficult to provide an indicator for this purpose, on account of the rotary arrangement of the storage device. On the other hand, an indicator is highly desirable.

This drawback is eliminated according to the invention by providing indicating members at that side of the numeral wheel shafts in the totalizer which is opposite the storage device, which members are arranged to be moved into and out of active position with respect to the shafts in dependence of the establishing opera-' tive and inoperativedriving relation between the totalizer and the storage device.

In the accompanying drawings, an indicator according to the invention is illustrated by way of example as adapted to a calculating machine of the type known as the Mercedes-Euklid.

In the drawings Fig. 1 is a perspective illustration of the machine.

Fig. 2 is a perspective illustration of the storage device and the indicator, viewed from the front of the machine.

Fig. 3 is a central vertical section of the carriage, as viewed in the direction of the arrow at r in Fig. 1, and showing the storage device in its disconnected, or inactive, position.

Fig. 4 is a similar illustration showing the storage device in its connected, or active, position.

Figs. 5 and dare elevations of mechanism arranged at the left-hand side of the machine dicating means in a machine whose totalizer shafts are not equipped with means for manual operation,.viewed from the rear of the machine.

Fig. 10 is a similar illustration of a device for the same purpose in a machine where the said means for manual operation of the totalizer shafts are provided.

Referring now to the drawings, and first to Fig. 1, the machine is enclosed in a casing and equipped with a keyboard for introducing values, and with special keys. Only the key it (S) and the canceling key i'l (SL) for the storage device come into consideration here. The carriage of the machine is arranged to slide in an elevated portion of the casing at the rear of the machine. The front wall of'the elevated casing portion has a row of holes 3a for reading the numeral wheels on the totalizer shafts, a second row 4 (Figs. 1, 9 and 10) for reading the numeral wheels of revolution counters on the totalizer shafts, and a third row 260 for reading the numeral wheels of the indicator.

Referring now to Fig. 3, the carriage 2 (Fig. 1) is mounted to slide on a pair of bars 84 through the medium of its upper rear plate 85 and its lower front plate 85'. An accumulator having sixteen orders is arranged on the carriage 2. Each order comprises a shaft 14 (Figs. 3 and 4) which is mounted to rotate in the plates, a. numeral wheel 3, a spur gear 1a below the rear plate 85 which meshes with the pinion Li which is driven by a rack L for. cancelling the values from the totalizer, and a spur gear 16 above the rear plate 85.

The storage device includes a shaft H which has a central longitudinal slot for the reception of the storage gears 15. The shaft H is mounted to rotate in bearings Ill (Fig. 2) at its ends 8! (Figs. 2, 5, 6) and 258 (Figs. 7, 8). The bearings 10 are secured to the front side of a plate 69, Fig. 2, whose both ends are secured to the frame of the machine. At its upper edge, the plate is equipped with a pair of prongs for each storage gear I5 which engage a teeth of each wheel when the storage device is in its inactive position, Fig. 3, holding the gears against turning.

The indicator comprises a frame 238 (Figs. 2 to 8) the front side of which arms 240 and 242 are secured by screws 239and 24!, respectively;

6, and of the right-hand end plate 246, Figs. 7

and 8, respectively, of the carriage 2'; sixteen headed screws 2" (Figs. 3, 4, 5, 6); a spur gear 234 with a numeral wheel 23! on each headed screw; and a retaining strip 231 between the heads of the screws and the spur gears 234.

An arresting plate 232 is secured to the rear plate 85 of the carriage 2 by long screws 23| (Fig. 2) and distance sleeves 233 on the screws, and connected to the frame 238 by springs 241 and 248 secured to the frame at 249 and 258, and to the plate 232 at 25] and 252, respectively. At its upper end the arresting plate 232 has pairs of prongs 233, one for each indicator spur gear 234. The springs 241 and 248 pull the frame238 toward the plate 232 until a tooth on each spur gear 234 has entered between the two corresponding prongs 233. This is the initial, or inactive, position of the indicator, as shown in Fig. 3.

The arm 243 at the left of the frame 233 has a rearwardly extending push rod 253 (Figs. 2, 5, 6) for cooperatijngwith a lug 254 on a crank 82 on the end 3| of the shaft 1|. At that end of the arm 248 which is secured to the frame 233 by the screws 239, ,a tooth 255 is arranged which also cooperates with the lug 254. A tooth 251 is keyed on the end 253 at the right-hand end of the shaft 1|, Figs. 7 and 8, and a rearwardly extending push rod 253 is provided on the other arm 242 of the frame 238, for cooperation with the tooth 251. A tooth 259 is arranged at that end of the arm which is secured to the frame 233 by the screws 2 for cooperation with the tooth 251. In the initial, or inactive, position of the storage device, as illustrated in Figs. 5 and '7, the end of the push rod 253 on the arm 240 bears against the lower edg of the lug 254 on the crank 82, and the tooth 251 engages the tooth 259 from below.

For canceling the values from the storage de-' vice 1|, a rack 31, Fig. 2, is mounted to slide in brackets 83 on the front side of the plate 39. The rack, to which reciprocation is imparted by mechanism operatively connected to the tens transfer shaft of the machine but not illustrated, meshes with pinions 90 which, in turn, mesh with the storage gears 15.

Referring now to Figs. 5 and 6, the crank 82 which is on the left-hand end 31 of the shaft 1 I, has a slot 83 in its free end in which engages a pin 48 at the upper end of a lever 45. The

lever and a link 43 (Figs. 5, 6) are mounted to swing on a headed screw 42 which is secured in the fram of the machine. A spring 44 connects the lever and the upper end of the link and pulls the lever against the upper end of the link. The link 43 has a slot 41 at its lower end in which engages a pin 40 at the upper end of a T lever 31. A lug 33 at the lower end of the T lever 31 engages in a notch 35 in the rear end of a connecting rod 33. The T lever is fulcrumed at 38. The front end of the connecting rod is pivotally connected to an arm 32 on the left hand end of a shaft 29 which is mounted near the front end of the machine frame. A spring 34 which is upwardly directed, pulls the connect... ing rod 33 to the rear and holds the bottom of its notch 35 against the lug 33 from below.

An arm 33 on the right-hand end of the shaft 29 is equipped with a headed screw 3| at its free end. The screw engages in a slot in the front end of a key lever 24 which at its rear end supports the storage key l3. The key lever 24 is fulcrumed at 25 and a spring 21 holds a projection 23 on the key lever against an abutmentnot shownand determines the initial position of the storage key.

When the key I3 is depressed, as shown in Fig.

6, the connecting rod 33 is pulled to the front and, through the means described, turns the lever 45 counter-clockwise. The pin 43 at the upper end of the lever turns the crank 82 and moves the storage device into its active position in which it is connected to the totalizers by its gears 15 meshing with the spur gears 13. While the storage device moves into active position, means operatively connected to the crank 32 move the indicator into its active position, as follows: When the crank 82 begins to turn, the lug 254 on the crank, and the tooth 251 release the noses 255 and 259 of the corresponding arms 240 and 242 and turn without effect through the distance 1/, whereupon they strike the upper edges of the push rods 253 and 258, respectively. The frame 238 is now turned about its screws 243 and 245 counter-clockwise, as viewed in Fig. 5, and against the urgency of the springs 24'! and 248 until the indicator spur gears 234 are in mesh with the totalizer spur gears 15, and are clear of the prongs 233 at the upper edge of the arresting plate 232.

The operation of the indicator will be fully understood from the following example:

At first it may be assumed that a value that is to say "144 has been introduced in the first three orders of the totalizer from the right at a previously calculating operation in a manner known by Mercedes Euklid calculating machines. When the canceling means L, Li and La (Figs. 3, 4) are operated, the three orders of the totalizer are returned to zero as described in the above mentioned Patent No. 2,173,635, the two first ones from the right rotating through four places, and the third one rotating through one place. The totalizer shafts 14 rotate clockwise, and so the storage gears 15 and the indicator spur gears 234 rotate counterclockwise, transferring the value I44 to the storage device and indicating it through the holes 238 of the cover plate 21. The accumulator key I3 is now released and springs,21 and 34 return the parts into their initial positions, Fig. 5, by turning the crank 82 anticlockwise. The lug 254 (Figs. 2, 5, 6) and the tooth 251 '(Figs. 7, 8) now release the indicator frame 238 which is now returned into its initial position by springs 241 and 243. Whenthe frame is nearly home, the lug 254 on the crank 82 and the tooth 251 act on the teeth 255 and 259 from below, accelerating the frame and making sure that the indicator spur gears 234 are disconnected from the totalizer spur gears 13 notwithstanding the rapid operation of the machine. Besides, the lug and the tooth lock the indicator frame in its inactive position. Otherwise, when the force of the springs 241 and 243 is momentarily weakened by an accidental shock, as may occur during the operation of the machine, the indicator spur gears might come into mesh with the totalizer spur gears 13 at the wrong time.

The values in the storage device are canceled by moving the rack 31 in the direction of the arrow a in Fig. 2 by depressing the canceling key 11 for the storage device. By means which have not been shown, the storage key I3 is depressed, as described in Patent No. 2,173,635, at the same time and the storage device is placed into active position. The canceling pinions 90 rotate the spur gears 15 of the totalizers anti-clockwise through the storage gears 15 so that the amount stored in the storage device is transmitted to the spur gears 284,.

Means are preferably provided for preventing engagement of the indicator spur gears 284 with the totalizer spur gears 1! in any other than the normal position of the carriage- 2. When the carriage 2 is moved to. the left from its normal position, as viewed in Figs. 9 and 10. the tooth 25! (Figs. 2, 5, 6) of the arm 2 moves away from the lug 254 and the tooth 2!! (Figs. 2,7,8)

of thearm 242 moves away from the tooth 2I1.-

Now if in such a position of the carriage, that is, in any position except its normalposition, the machine undergoes a shock, for instance, if its rear feet have been inadvertentlyplaced on a book or the like, and the machine slides off the book and onto the table, the force 'of the springs 241 and 248 is weakened momentarily, and the spur gears 23! may get into mesh with the spur gears 16, so that the indications in the holes 260 are wrong. Such accidents are avoided'by the devices illustrated in Figs. 9 and 10.

' Referring now to Fig. 9, the retaining strip 221 on the indicator frame 230 is recessed at'two points 261. In the normal position of the car-"- riage 2, hooks 210 at the upper ends of two stops 2" are opposite the recesses 281. The stops are secured to the rear'side of the plate 89 by screws 266. In the normal position, that is the position wheel as which are rotated clockwise by the spur gears 18 of the totalizers through their own at the left-hand end of its stroke, as viewed in Fig. 1, of the carriage 2, the stops 26! do not interfere with the movement of the indicator into its active position, whose direction is indicated by the arrow 268 in Fig. 5, but when the carriage 2 is in any other than its normal position, the

' lower edge 269 of the retaining strip 231 is arrested by the end 210 of the stops 265, and the indicator spur gears 2 cannot mesh with the totalizer spur gears 16.

Referring now to Fig. 10, the shafts 14 of the totalizer gears are extended beyond the spur gears 15, and equipped with knurled handles 16a for turning the shafts. Obviously, stops like 265, which are secured to the plate 69, would interfere with the movement of the carriage 2. In this case, therefore, stops 215 are'secured to the carriage by screws 21!, and a strip 212 is secured to the plate 89 by screws 2". and recessed at 213 opposite the free ends of the stops 215. When the carriage is in its normal position, the recesses 213 are presented to the stops, and movement in the direction of arrow 26! is not interfered with, but in any other position of the carriage the stops are arrested by the straight edge 213a of the strip 212,
